Deforestation is a major threat of Bangladesh. Deforestation means cutting down trees in large number. The causes of deforestation are many. According to the ecologists, for liveable environment there should be forest on the 25% land of the total area. In Bangladesh there is 16% forest of the total land. Bangladesh is the most densely populated country in the world. Its population is much more in proportion is its area. This huge number of population needs more shelter, agricultural land, fuel, furniture etc. For all these reasons people cut trees. Moreover there are some dishonest people who cut trees in our forests to make money. They effects of deforestation are too many to describe. This destruction disturbs our ecological balance. The existences of animals are going to be threatened. Due to deforestation carbon dioxide is increasing worldwide. As a result, the world is becoming warmer. The sea level is rising and many parts of the world are going to be engulfed by the sea in recent future. On the other hand, new areas of the world are turning into deserts as a result of deforestation. The removal of trees causes birds and other animals living on them to leave the place. It also causes serious damage to the soil, as trees give protection to soil as well. In the end, the soil gets sediment in the river bed and causes frequent floods. So, if we destroy trees at random, one day Bangladesh will turn into a great desert. All living animals and birds will not find any food or shelter to live in. they will destroyed. There will be no rain and as a result Bangladesh’s agriculture will face a great crisis. The temperature will rise and it will cause green house effect. Bangladesh will be unsuitable for living and various natural calamities like flood, drought, storm etc. will visit our country. Immediate measures should be taken to prevent deforestation. People should be made aware of tree plantation through mass media. Tree plantation programme should be extended throughout the Bangladesh.
